Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Bun

  • Linux requires kernel 5.6 or higher (5.1 minimum but with compatibility issues); older systems not supported
  • Native Node.js addons not supported directly; requires FFI workarounds for C libraries
  • Ecosystem less mature than Node.js; fewer third-party packages optimised for Bun
  • Windows support newer and less mature than Linux/macOS; occasional edge cases

Dynatrace

  • Pricing is commitment based: rates require an annual platform level commitment rather than month to month purchase
  • Full-Stack Monitoring is priced at $58 per month per 8 GiB of host memory, so a 64 GiB host counts as eight units
  • Infrastructure Monitoring at $29 per host per month excludes code level tracing, which requires Full-Stack
  • Session Replay doubles Real User Monitoring cost from $2.25 to $4.50 per 1,000 sessions
  • Runtime Vulnerability Analytics and Runtime Application Protection are each charged separately at $13 per month per 8 GiB host on top of monitoring
